Be in Shape to Drive (Chapter 10)

TL;DR

Impairment and fatigue slow reactions and judgment—check meds, plan rest, and minimize distraction overlap.

Scope

Physical, mental, and impairment factors affecting driving: alcohol, drugs (prescription & illicit), fatigue, emotion, distraction interplay. Verify legal BAC limits and any zero-tolerance age specifics in official guide.

Learning Objectives

  • Recognize impairment types and their effects on reaction time & judgment.
  • Identify fatigue signs and mitigation strategies.
  • Understand medication & driving risk consultations.
  • Apply distraction management techniques.

1. Alcohol & Drug Impairment

  • Slows reaction, narrows focus, impairs judgment.
  • Mixing substances compounds effects unpredictably.
  • Designate driver or alternative transport before consuming.

2. Medication Awareness

  • Review labels for drowsiness warnings.
  • Consult pharmacist/doctor about combining meds and driving.
  • First-dose caution: Evaluate personal reaction before driving.

3. Fatigue

  • Signs: Yawning, drifting, delayed response, microsleeps.
  • Mitigation: Adequate sleep, breaks every ~2 hours, avoid late-night long drives.

4. Emotional State

  • Anger or stress can trigger aggressive driving.
  • Strategy: Pause, deep breathing, delay trip if severely agitated.

5. Distraction Interplay

  • Cognitive (mind off task), manual (hands off wheel), visual (eyes off road).
  • Use phone only in permitted hands-free manner; avoid complex interaction.

Impairment factors

Impairment factors: Alcohol/Drugs, Fatigue, Medications.
Stacked factors compound risk—plan rest and review meds.

Quick Self-Check

3 things to remember

  • Be cautious with first-dose or drowsy medications before driving.
  • Fatigue signs (yawning, drifting, microsleeps) demand breaks or trip delay.
  • Distraction types: visual, manual, cognitive—avoid stacking them.

Quick Flashcards

Quick Review

Why avoid driving after a first dose of some meds? You don't yet know how they affect alertness or reaction time.
Two fatigue warning signs? Yawning, lane drifting, or microsleeps.
Name the three distraction types. Visual, manual, and cognitive.
